I think some of the entries are also more US-specific. (Although I do see some entries making reference to specifically Canadian things.) For example, the race landscape is totally different in Canada than in the US; we have nothing corresponding to the US black population (blacks in Canada are AFAIK typically immigrants from Africa or the Caribbean), nor US immigrant Latino populations. Major non-white ethnic groups in Canada are east Indian, Asian (especially Chinese), and North American native. And then the race and class interaction issues are completely different, since Indians and Asians are (AFAIK) not really perceived as having particular barriers to entering the middle class or professional class, i.e. they're not perpetual-underclass minorities, whereas with natives, it is something much more like a perpetual underclass excluded from the middle class mainstream. So things such as "having a black friend" don't really apply in the same way in Canada because it just wouldn't have the same significance, and because there are much fewer blacks and they don't form a distinct culture the way American blacks do, but are just another among many small ethnic minorities. And "having an Asian friend" or "having an Indian friend" wouldn't be anything like equivalents either.
